Abstract

The embodiment of the invention discloses a display device and electronic equipment. The display device includes: a fingerprint identification module, which includes a plurality of fingerprint identification units; and a light collimation film layer, which is located on the fingerprint identification module, includes at least one first medium layer and at least one second medium layer arranged ina spacing and layer stacking manner, and is used to enable fingerprint reflecting light in a set incidence angle to be transmitted and transmittance to be greater than or equal to preset transmittance, wherein the first medium layer and the second medium layer are different in thickness and refractive indexes, n1*d1=n2*d2, n1 is the refractive index of the first medium layer, n2 is the refractiveindex of the second medium layer, d1 is the thickness of the first medium layer, and d2 is the thickness of the second medium layer. In the embodiment of the invention, the light collimation film layer is arranged on the fingerprint identification module, and can reduce a loss of the light transmittance, avoid generation of moire, reduce crosstalk signals of fingerprint identification, improve accuracy and precision of fingerprint identification, and realize a needed light collimation effect.

Description

technical field [0001] Embodiments of the present invention relate to display technologies, and in particular, to a display device and electronic equipment. Background technique [0002] Fingerprints are inherent to each person and are unique. With the development of technology, a variety of display devices with fingerprint recognition functions appear on the market, such as mobile phones, tablet computers, and smart wearable devices. In this way, before operating the display device with the fingerprint recognition function, the user only needs to touch the fingerprint recognition sensor of the display device with a finger to perform authority verification, which simplifies the authority verification process. [0003] In the existing display device with fingerprint identification function, when the light emitted by the fingerprint identification light source is reflected by the finger, it will be irradiated on a plurality of fingerprint identification sensors, so that each ...
